Application led November 15,11888. Serial No. 290,90?. tINo model.)

To all whom it may concern:

Be it known that I, GURDON CONKLING, a citizen of the United States, residing at Glens Falls, in the -county of Varren and State of' New York, have invented newand useful Improvements in Magnetic Separators of which the following is a specification.

This invention relates to certain improvements in that class of magnetic separators which I have described in Letters Patent No.

383,863, granted to me June 5, 1888, said im provements being pointed out inthe following specification and claims, and illustrated in the accompanying drawings, in Which-,

Figure 1 is a longitudinal vertical' section 1n the planea w, Fig. 3. Fig. 2 is a transverse vertical section in the plane y y, Fig. 3. Fig. 3 is a plan or top View, some portions being broken away in order to show the parts be'- low.' Fig. 4 is a the covers.

Similar letters indicate corresponding parts.l A In the drawings, the letter A designates a upon them, as shown in the drawings. .The l magnets F are secured' to traverses F which are connected by screws a a to the frame A, -screws the magnets so that by means of said can be raised or lowered.

vA hopper H. is placed in suitable relative position to the transverse belt C, (see Fig. 2,)

.and a brush 'or scraper I acts onsaid transverse belt. Suitable receptacles J K are provided-one for the concentrated ore or iron -particles and the other for the gangueor refuse.` A beltP, which extends round pul- --leys L M, is made to impart motion'to the feed-belt D and also to the transverse belt C.

The Afeed-beltl) is provided with raisedy rims perspective View of one ofy Y Over the feedingsection of the belt D, or

-over that portion of the same which is'sit'u-Q b b, which prevent the'l material to be trea v' 5o from passing olf over the edges of said bet! ated betweenI thehopper E and the magnets F, is placed a cover N, which is held in position lby screws z' t' or other suitable fastenings,

and which extends a certain distance beneath the edge vof the transverse belt. When the pulverized ore, which is fed through the hopper'E upon the feed-belt D, is carried by this 'belt toward the transverse belt C, fine parti- `cles of iron are liable `to be attracted by the magnets F and to be'carried bythe force ofsuch attraction over the edge of the transverse belt. `This disadvantage is guarded againstbythecover N. `The discharging..

section vof the feed-belt D is covered by a'y cover O, Vwhich extends a certain 'distancej over the vedge of the transversebeltG',and

which prevents iron particles contained in dthe v mass carried by the feed-belt from being car-r ried over the edge of the transverse belt by' the attraction of the magnets F.

The cover N is provided with flanges am, i

(best seen in Fig. 4,) and 'if the feed-belt D is provided with raised rims'b b said nanges fnn.

extend down onthe inside ,ofthe Lrims b b when the cover N. is adjusted in its Working position. (See Fig. 2.)4 By the combined a action of the rims b b and of the iianges the material carried by the feedl'ieltDisv prevented from passing over theedges of, said belt, andi even the dust, which may become.

disengaged from said material by the rapid" motionv of the feed-belt and by the jar of the causing annoyance.

The magnetsF extend in the direction 'ot` the length of thegtransverse belt C, and eon-` i sequently in a transverse direction to the feedbelt D, Figs. 2 and '3,`and their length is such` 8s machine, willk be prevented from rising npand that their ends extend beyond the edges of vplaced transversely across the transverse belt C, 'the iron particles attracted by said magnets are liable to remain stationary While the belt-C continues .to move, and asv the mass of the particles attracted by the magnetsinby Letters Patent, is-

l. The combination, with the feed-belt, the transverse belt, and the magnet or magnets contained in said transverse belt, of'a cover extending over the feeding-section of the feedbelt, substantially as described.

.2. The combination, with the feed-belt, the

transverse belt, and the magnet or magnets' contained in said transverse belt, of a cover extending over the feeding-section of the feedbelt and beneath the edge of the transverse belt, substantially as described.

3; .The combination, with the feed-belt, the transverse belt, and the magnet or magnets contained in said transverse belt, of Vtwocovers, one extending over the feeding-section and the other over the discharge-section of the feed-belt, substantially as described.

4. The combination, with the feed-belt, the transverse belt, and the magnet 0r4 magnets contained in said transverse belt, of two cov* ers, one extending over the feeding-section contained in sad transverse belt, of a cover provided on its under surface with flanges and extending over the feeding-section of the feed-belt, substantially as described.

6. The combination, with the feed-belt having raised rims' at its edges,.and with Vthe transverse belt and the magnet or magnets contained in ,the transverse belt, of a cover provided with flanges 'n n and extending over the feeding-section oi' the feed-apron, substantially as described.

In testimony whereof I lia-fe hereunto set my hand andseal in the presence of two subscribing witnesses.

GURDON CONKLING.
